Abstract (en)
[origin: EP0443886A1] The invention concerns an assembly of a braking assistance servomotor and a master cylinder comprising in an outer casing (10) a volume divided in a fluidtight manner into a front chamber (12) and a rear chamber (14) by a mobile partition (16), at least a first elastic means (18) tending to displace the mobile partition towards the rear chamber, the front chamber being connected to a vacuum source, a pressure difference being established between the front and rear chambers by a valve means (20) capable of connecting the rear chamber to the atmosphere when a control rod (22) is actuated in order to displace the mobile partition towards the front chamber, a master cylinder (30) fixed to the front of the casing and comprising a bore (40) in which slides, in a fluidtight manner, a push rod (42) integral with the mobile partition and delimiting an enclosure (28) in the master cylinder, this push rod comprising a bore (32) in which slides, in a fluidtight manner, a reaction piston (24) subjected to the pressure in the enclosure (18). According to the invention a second pre-stressing elastic means loads the said piston towards the master cylinder. <IMAGE>
